An e-reader can carry a whole library wherever you go, which is great for travelers or those who always want a choice of reading material Although e-readers are convenient, high levels of screen brightness from an electronic device(电子设备) can cause eye problems. A study in the Information Science Research found that young people preferred e-readers, like smart phones or iPads. That’s why most teenagers are short-sighted.
Many book lovers still prefer paper books and value the feeling of them. Paper books are very well designed, they look and smell good, and they carry with them a more human touch. Avid (热衷的)readers prefer reading on paper. Perhaps this is their choice because paper books give them a sense of ownership. It is reported that reading on paper rather than an electronic screen is better for memory and focus. But paper books are heavy and they are not convenient to carry.
Which is your decision, an e-book or a paper book?

The Seed Vault (种子地窖)
A lot of countries need different kinds of seeds so that they can plant them again. There is an important reason for this. Sometimes plants can’t grow in a country because of bad weather or disease, so farmers need new seeds. You can keep seeds in a “seed vault”. It’s a place at a special temperature. The seeds don’t grow, but they can live for a long time. Do you know Norway has the biggest seed vault in the world—the Svalbard Global Seed Vault? It has seeds from a lot of different countries. Let me tell you something about the Svalbard Global Seed Vault.
The vault is on the island of Spitsbergen. The island is about one thousand kilometers from the North Pole. It’s a very cold place so it’s good for seeds. Above the ground, the doorway is small, but inside, the building is huge. You walk down a long corridor (走廊), which is one hundred and thirty meters inside a mountain. At the end of it, there are three large areas with seeds.
There are about half a million kinds of seeds inside the vault. For example, there are kinds of seeds for rice from Asia and Africa, 32 kinds of seeds for potatoes from Ireland and seeds for different tomatoes from the USA.
The seed vault has space for a lot more seeds. You can put about 2.2 billion (十亿) seeds inside. The seeds can live here for thousands of years because of the cold temperature of -18℃. So, in the future, humans can grow any seed they want. In other words, the seed vault is the difference between life and death.

【推荐3】Memory is very important. It helps you remember who you are, where you live, what you have learnt and what you plan to do in the future.
Some scientists believe that there are three types of memory—immediate, short-term and long-term.
Immediate memory holds information for less than a second, e.g. the name of a road you have just seen. Then it either forgets it or passes it into short-term memory. Short-term memory can hold about seven items of information at a time, e.g. telephone numbers. It holds them for about 30 seconds. Then it either forgets them or passes them into long-term memory. Long-term memory can hold information for the whole of our lives, e.g. the names of countries or the meanings of words.
So, how can you improve your memory?
It is important to exercise your brain. For example, you can do new things and change your daily habits. If you walk a different way to school or take a different bus, you will keep your brain active. You can try to memorize something new. You can try a Maths puzzle（益智游戏）. You can also try to learn new skills or study a foreign language. Your brain gets lots of regular exercise if you do any of these things.
If you live a healthy life, your memory will work better. You must have a balanced diet（均衡的饮食）. You must give your brain enough time to rest. Unless you get enough sleep every night, you will not remember things well.
If you want your brain to work well, you also need to relax. If you get too worried, your brain will slow down, and your memory will become less excellent.
So, to improve your memory, you should exercise your brain, live a healthy life and stay relaxed.
